Who developed the radiocarbon dating method

Rated 3.91/5 based on 752 customer reviews

The most recent addition to the battery of techniques is cosmogenic nuclide dating, which has been around for only two decades.Each technique is limited in the type of material that can be dated and the time range over which it can be applied.Thus, it is possible (and, given the Flood, probable) that materials which give radiocarbon dates of tens of thousands of radiocarbon years could have true ages of many fewer calendar years. The shells of live freshwater clams have been radiocarbon dated in excess of 1600 years old, clearly showing that the radiocarbon dating technique is not valid.The shells of live freshwater clams can, and often do, give anomalous radiocarbon results.Some of these, such as radiocarbon and potassium argon dating, have been around for more than 50 years and are widely accepted.Other methods, such as those based on cumulative effects of radioactive decay, have been around for somewhat less time.

It is not correct to state or imply from this evidence that the radiocarbon dating technique is thus shown to be generally invalid.Since limestone contains very little, if any, radiocarbon, clam shells will contain less radiocarbon than would have been the case if they had gotten their carbon atoms from the air.This gives the clam shell an artificially old radiocarbon age.A large number of techniques have been developed that can provide a timescale for processes that take place during the Quaternary.Many numerical dating methods had their early roots in the enthusiastic study of radioactive decay as a means of obtaining the age of the Earth.
